QUILLING MACHINE.

.Application filed January 30, 1926. Serial No. 84,877.

This invention relates to machines for winding yarn or thread into theform of compact packages (as for use in shuttles), commonly known asquilling machines. One

of the principal objects is to obtain increased production by increasingthe winding speed and .to this end instead of obtaining the raversene.:essary in winding this class'of packages from a rocker arm I utilizea barl0 rel cam in a novel way to be indicated, thus avoiding thevvibration which characteristic of aV rocker arm or equivalent and is anobstacle to high speed. Another object is to improve the means forestablishing and ailisestablishing the connection between the mainrotary drivingl element and the rotary moans driven thereby. Anotherobject is to proviile for a nice adjustment, one toward the other, asbetween 'the package spindle 2o and the rot ary friction wheely formingApart of tbe thread-giriding mechanism. Another object is to constructthe machine so that when automzfitic stopping is effected the burning ofthe package may be avoided'. Another object is to provide forlubrication which shall be at once adequate and avoid deposit of thelubricant on exposed parts.

I show in the drawing one complete quill'- ing unit of the machine,

Fig. 1 being a vertical' longitudinal section of a quilling unit takenin the plane of the push-rod;

2 a plan, a certain shield' 41 being removed;

Fig. 3 a vertical section in the plane of line 3 3, Fig. 1, lookingforward; and

Figs. 4 and 5 vertical sections in the plane of line 4 4, Fig. 1', andrespectively looking forward and rearward.

r1 support for the working parts is afforded by a generally rectangularhousing 1 having a removable cover 1La and' a rearwardly ilirojectingyoke 2 affording a bearing. In the yoke is journaled` the drive-shaft 4'Car- 45 rying` a pulley 5 through which, from a suitable belt andsubstantially after the manner shown for example in my Patent No.1,457,294, shaft 4 andv other rotated parts of the unit are driven.Shaft 4 carries at its 50 inner end', within the housing, the receivingmember (i of a cone-clutch, and it is bored to receive and form a rearbearing for the spindle 'l' which is journaled near its forward end in abearing S on the front wall ofthe housing; the spindle reciprocated aswell as rotated in these bearings. The spindle has a clinch-memberforming the received memlgier of the clutch and movable length'- wise ofthe spindle (to make and break the clutch) independently thereof butwhich turns with the spindlethe connectionA between them being in effecta spline-and comprising a conical head' or clutch-member proper 9, thehead 1.0, formed with a peripherally grooved collar 10d and longpinion10b, and two rods 11 rigidly connecting the heads, the mentionedspline-connection be tween the Spindle and head beingv afforded by across-head 12 fixed on the spindle and penetrafed by the two, rods whichslide therein. Shifting of the clutch member last described into or theclutch `member 6 of course results in the spindle being rotated by thedrive-shaft or left free thereof. For effecting this shifting there is afork 13 engaged with the collar 10a and having its sleeve or barrel 13aslid? able on the push-rod 14, being normally urged rearwardly and sotending to holdV the clutch engaged by a spiral spring 15 coiled aboutthe push-rod and interposed between said sleeve and a bearing 16 for thepushrod. which also has aI bearing in the front wall ofthe housing; whenthe push-rod moves forward a. collar 14al thereon encoun ters the sleeveand retractsthe fork (to break the clutch), but when the push-rod isrepressed spring 15 becomes active to yieldingly hold the receivedagainst the receiving clutch member. The push-rod is capable of rockingslightly in its bearings and has a bell-crank lever 17 fixed thereon,one arm 17'aL of which limits this rocking by being interposed between afixed stop 18 and one side of the housing. said stop having astopshoulder at 18a. rlhe push-rod is normally heldl pressed forward andalso rotatively in the direction to bear laterally against the stop by acombined tension and torsion spring 19 which is coiled about it andsecured thereto by the screw 19a and also to the bearing 16, said springbeing stronger than spring 15. l/Vhen the push-rod is repressed by meansof its knob 14b and to the limit afforded by vcontact of a collar 14cthereon with housing a spring 19 turns it and it becomes locked byengagement of its lever arm 17d with the stop-shoulder of the out ofengagement with y stop, and this establishes the shiftable clutch memberin yielding pressure engagement with the other clutch member; when thepush-rod is turned to disengage its lever arm from said slop-shoulderthe push-rod springs forward and disestablishes the clutch-connection.

A barrel. cam Q() is journaled on the spin dle between two collars 2land Xed thereon and receives a stud 23 (having a roller 24 thereon)fixed to the housing. The cam has a gear 20 and rotary motion is transmitted to said gear and hence the cam from pinion 10b through acounter-shaft 25 journaled in bearings a and Q5" and having a gear 26 inmesh with 10b and a long pinion 27 in mesh with 20. The gearing is suchthat the rotary motion imparted from pinion l0b to the cam is suitablyless than that of the rotary structure including the spindle andreceived clutch member with the result that the traverse rate of thespindle is less than its revolution rate.

The construction of the thread guiding mechanism may in general followthat set forth in prior patents to me (for example, No. 1178045), thatis to say: The threadguide rod 28, slidable lengthwise in the housing,is adapted to be moved by the rotary threaded rod 29 having africtionwheel 29a' and a collar 29h with which a fork 28a fixed on therod 28 is engaged; rod 29, due to intermittent contact of the peripheryof the friction wheel with the package being wound and reciprocatingwith the spindle, is intermittently rotated and thus gradually fedforward by having its threading engaged with the peripheral teeth of aperipherally grooved wheel or nut 30 normally held against rotation byfriction means, as the spring washer 30a, but capable of rotating if therod is forcibly shifted, as in setting it back to start winding anew.This nut device and a companion plain grooved roller 3l which. keeps therod engaged with its teeth (Fig. 5) are journaled in a bracket 32arranged to slide on two parallel shafts 33 the upper one of which isrotary and threaded. the upper end of the bracket being formed as a nut32a engaged with the threading of this shaft: this threaded shaft has amilled knob 83 for turning it and so adjusting the bracket laterally.Rod 29 passes loosely through a hole 34 (Fig. 3) in the front wall ofthe housing and it has a bearing in a ball 35 jonrnaled in the upper endof the bracket 36 suitably supported at the front of the housing, suchbearing also affording a fulcrum for the rod around which it may beadjusted by turning the threaded shaf 33 to advance nut 32a one way orthe other. After adjustment of the threaded rod lever-fashion (with theball as the fulcrum) to obtain the desired degree of pressure of thefriction wheel against t-he windings the parts as adjusted are heldsecurely in position by tightening a screw (Fig. 9.) which causes thenut 32, which is split, to clamp the threaded shaft. The adjustabilityof the means (as 32") to engage the threading of the rod laterally withthe rod is new' in the art.

The stopping of the wiinling when the package is full has heretoforebeen accomplished in these machines by causing a cone on the threadedshaft to engage an arm or crank on the push-rod and so turn the latterfor tripping the same whereby to break the clutch connection. It isdesirable to make the trippiinT as quick and to effect it with as littleincidental resistance to the rotation of the threaded rod as possible inorder to avoid undue rubbing of the friction wheel against andconsequent burning of the silk or other material of the package. Hencethe arm or crank, here afforded by the arm 17" of the bell crank lever17, is equipped with a lever 38, one arm of which (preferably heavierthan the other) overhangs the threaded rod and the other the spindle 7,and the collar 9.1 on the spindle is formed as a cone and the rod alsohas a cone 39. When the rod advances sufficiently its cone 39 engages and tilts the lever more and more until finally a point is reached wherein a forward movement of the spindle cone 2l impinges against said leverand elevating it on cone 39 as a fulcrum trins the lever 18. Thetripping is thus not only instantaneous but7 because of the interposingof a lever (38), the frictional resistance on cone 39 and henceresistance to rotation of the threaded rod and friction wheel are verymaterially reduced.

The housing` forms at its bottom a reservoir for liquid lubricant, whosemaximum level is indicated by the horizontal dotted line in Fig. l, 40being` the lubricant filling inlet. Gear 26 rotates in this lubricant atsuch speed that it throws the lubricant up against a shield l1consisting of a plate extending fr-om one side of the housing over anddown beside the gearing; and secured to the housing by screws 42. Thelubricant is splashed by gear 26 against this shield with such forcethat it is largely sprayed back onto the rest of the gearing, thuskeeping all moving parts lubricated. The top portion of the shieldslopes backward and downward, so that the excess lubricant clingingthereto by capillary attraction runs backward to then drip back into thereservoir at the rear end of the shield; if the drip were allowed toensue forward the lubricant would work forward out of the housing. sothat the exposed parts would become oily and the product of' thewindingwould be likely to be damaged.

rlhe operation is in general the same as usual in quilling machines inwhich the {laaiend-guiding4 meansfis' gradually' fed along by rotation,ind-need by the package, ot its threaded rod as' the spindle is:reciprocated. F or startingr to Wind' the push-roelis repressed'I andbecomes locked ini the rearward position, thus establishing theclutch-en:- gagement whichy causes the 'spindle to be rotated and also,thro-ugh thel gearing, the cam, which, coacting with stud 23 and actingalternately against the collars 2L and 22 on the spindle, reciprocatesthe latter, the rate of reciprocat'ion being suitably less than therevolution rate o't the spindle a'ccording to the gearing. Then in thead.- vance of theV thread-guiding means as the package builds up thelever 8S is actuated as explained to release the push-rod the-same inmoving imward' disestablishes the clutch andy stops the Winding.
